Description
Summary:Invasive exotic species impact native fauna adversely and are one of the leading causes of global biodiversity change. The domestic dog can be classified as an invasive species after its access to natural areas followed by their ability to survive independently of human intervention. In Brazil, the effects of dog predation and hunting on wildlife remains unclear. In this study, we report five wild-mammal predation events involving domestic dogs in fragments of the Brazilian Atlantic Forest (northern Paraná State, Brazil). Between June and September 2018, we found that specimens of Didelphis albiventris (white-eared opossum), Dasypus novemcinctus (nine-banded armadillo), Sapajus nigritus (black capuchin), and Eira barbara (tayra) were killed by domestic dogs in both urban and rural areas. Invasive domestic dogs can pose a risk to wildlife, especially to threatened species. We suggest that diversified measures be taken to impede and reduce the access of these animals to forest fragments. Furthermore, our findings indicate that control, containment, and eradication measures can reduce the negative effects of domestic dogs on wildlife. O impacto de espécies exóticas sobre a fauna nativa está entre as maiores ameaças à biodiversidade global. O cão doméstico é considerado invasor quando acessa áreas naturais, podendo sobreviver independentemente da intervenção humana. No Brasil há poucos estudos com informações sobre o impacto da predação ou caça de cães sobre a fauna silvestre. Relatamos cinco eventos de predação de mamíferos silvestres por cães domésticos em fragmentos da Mata Atlântica na região norte do estado do Paraná, Brasil. Entre junho e setembro de 2018, espécimes de Didelphis albiventris (gambá-de-orelha-branca), Dasypus novemcinctus (tatu-galinha), Sapajus nigritus (macaco-prego) e Eira barbara (irara) foram abatidos por cão doméstico tanto em fragmentos de área urbana quanto de rural. Cães domésticos oferecem riscos à fauna silvestre inclusive àquelas espécies ameaçadas de extinção, sendo de extrema ...
